Too early to assure about curvature correction since I’ve been on DMSO for couple of months. TG could explain it better, but I believe that changes in curvature takes a very long time.
Major concern about DMSO and pumping is the interaction between the DMSO, which is an solvent, with the cylinder. I use Leluv and they are made of ABS plastic, which apparently doesn’t react and is ok to proceed.
My penis is dry before I start pumping and the feeling and indicators are about the same as stock pumping.
Since I start with DMSO just noticed that at flaccid state my penis feels way softer than before.
